Question

6. Which equation represents the equation that passes through the given points:

(1,5) & (3,-3)
A. y = 2x + 3
B. y = -4x +9
C. y = 2x – 9
D.y = - 4x +3

Answer 1

The answer is B

Find slope

y2 - y1

Formula: x2 - x1

Just plug in values

Slope will be -4

Take equation and plug in a point

Equation: y = mx + b

Plug in 5 = -4(1) + b

5 = -4 + b

+4 +4

9 = b

y = -4x + 9
